How can I display a Save As dialog in an Electron App?

Question

I am writing a NodeJS Electron App to be distributed on all platforms. I have a download button that I would like to pop open a Save As dialog with the file being provided from

Answer 1

On the HTML button:

Save As

In your javascript file:

// Include in the render side
var elerem = require('electron').remote;
var dialog = elerem.dialog;
var app = elerem.app;

var http = require('http');
var fs = require('fs');
var path = require('path');


function myUrlSaveAs(remoteUrl){
    // app.getPath("desktop")       // User's Desktop folder
    // app.getPath("documents")     // User's "My Documents" folder
    // app.getPath("downloads")     // User's Downloads folder

    var toLocalPath = path.resolve(app.getPath("desktop"), path.basename(remoteUrl) 

    var userChosenPath = dialog.showSaveDialog({ defaultPath: toLocalPath });

    if(userChosenPath){
        download (remoteUrl, userChosenPath, myUrlSaveAsComplete)
    }


}

function myUrlSaveAsComplete(err){
    alert("done");
}


function download (url, dest, cb) {
    var file = fs.createWriteStream(dest);
    var request = http.get(url, function(response) {
        response.pipe(file);
        file.on('finish', function() {
            file.close(cb); // close() is async, call cb after close completes.
        });
    }).on('error', function(err) { // Handle errors
        fs.unlink(dest); // Delete the file async. (But we don't check the result)
        if (cb) cb(err.message);
    });
};
